Natural World Heritage Sites Threatened by Climate Change

Number of Natural World Heritage Sites Affected by Climate Change Nearly Doubles in Three Years – IUCN

Bonn, Germany, 13 November, 2017 (IUCN) – The number of natural World Heritage sites threatened by climate change has grown from 35 to 62 in just three years,
with climate change being the fastest growing threat they face, according to a report released today by IUCN,
International Union for Conservation of Nature, at the UN climate change conference in Bonn, Germany.

The IUCN World Heritage Outlook 2 – an update of the 2014 IUCN World Heritage Outlook report – assesses, for the first time, changes in the conservation prospects of all 241 natural World Heritage sites.
It examines the threats, protection and management of the sites, and the state of their World Heritage values – the
unique features which have earned them their prestigious World Heritage status.

According to the assessments, climate change impacts, such as coral bleaching and glacier loss, affect a quarter of all
sites – compared to one in seven sites in 2014 – and place coral reefs and glaciers among the most threatened
ecosystems. Other ecosystems, such as wetlands, low-lying deltas, permafrost and fire sensitive ecosystems are also
affected. The report warns that the number of natural World Heritage sites affected by climate change is likely to grow
further, as climate change remains the biggest potential threat to natural world heritage.

“Protection of World Heritage sites is an international responsibility of the same governments that have signed up to the
Paris Agreement,” says Inger Andersen, IUCN Director General. “This IUCN report sends a clear message to the delegates gathered here in Bonn: climate change acts fast and is not
sparing the finest treasures of our planet. The scale and the pace at which it is damaging our natural heritage
underline the need for urgent and ambitious national commitments and actions to implement the Paris Agreement.”

World Heritage-listed coral reefs, such as the Aldabra Atoll in the Indian Ocean – the world's second-largest coral
atoll, the Belize Barrier Reef in the Atlantic – the largest barrier reef in the northern hemisphere, and the Great
Barrier Reef – the biggest reef on Earth, have been affected by devastating mass coral bleaching events over the last
three years, due to rising sea temperatures. The Great Barrier Reef, for instance, has suffered widespread bleaching,
with up to 85% of surveyed reefs impacted in 2016.

Retreating glaciers, also resulting from rising temperatures, threaten sites such as Kilimanjaro National Park – which
boasts Africa’s highest peak – and the Swiss Alps Jungfrau-Aletsch – home to the largest Alpine glacier.

“Natural World Heritage sites play a crucial role supporting local economies and livelihoods,” saysTim Badman, Director of IUCN’s World Heritage Programme. “Their destruction can thus have devastating consequences that go beyond their exceptional beauty and natural value. In
Peru’s Huascarán National Park, for example, melting glaciers affect water supplies and contaminate water and soil due
to the release of heavy metals previously trapped under ice. This adds to the urgency of our challenge to protect these
places.”

The broader findings of the report show further challenges to World Heritage. Other threats, such as invasive species,
unsustainable tourism or infrastructure development, are also increasing. They affect ecological processes and threaten
the survival of species within the sites. Invasive alien species are the most widespread of all threats. Their impacts
are often aggravated by climate change, which facilitates their spread and establishment.

Overall, the report finds that 29% of World Heritage sites face significant concerns and 7% - including the Everglades
National Park in the U.S. and Lake Turkana in Kenya – have a critical outlook. Two-thirds of the sites are assessed as
likely to be well conserved in the near future, the same overall proportion as in 2014.

The report also reveals that the management of natural World Heritage sites has dropped in quality and effectiveness
since 2014, notably due to insufficient funding. Fewer than half of the sites are currently being managed to good
standards.

However, the report also includes some success stories, which show tangible, positive impact of effective management.
Côte d’Ivoire’s Comoé National Park, for example, has seen the recovery of its elephant and chimpanzee populations
thanks to effective management and international support, following political stabilisation in the country. As a result,
its conservation outlook has significantly improved over the last three years. It is one of 14 sites with an improved
rating since the 2014 IUCN World Heritage Outlook report.

IUCN is the official advisory body on nature under the World Heritage Convention. Natural World Heritage sites are
globally recognised as the world’s most important protected areas, inscribed on the UNESCO World Heritage List for their
unique natural values, such as the scale of natural habitats, intactness of ecological processes, viability of
populations of rare species, as well as exceptional natural beauty.

IUCN is a membership Union uniquely composed of both government and civil society organisations. It provides public,
private and non-governmental organisations with the knowledge and tools that enable human progress, economic development
and nature conservation to take place together.

Created in 1948, IUCN is now the world’s largest and most diverse environmental network, harnessing the knowledge,
resources and reach of 1,300 Member organisations and some 10,000 experts. It is a leading provider of conservation
data, assessments and analysis. Its broad membership enables IUCN to fill the role of incubator and trusted repository
of best practices, tools and international standards.

IUCN provides a neutral space in which diverse stakeholders including governments, NGOs, scientists, businesses, local
communities, indigenous peoples organisations and others can work together to forge and implement solutions to
environmental challenges and achieve sustainable development.

Working with many partners and supporters, IUCN implements a large and diverse portfolio of conservation projects
worldwide. Combining the latest science with the traditional knowledge of local communities, these projects work to
reverse habitat loss, restore ecosystems and improve people’s well-being.
